I have used that kit, it was far superior to any of these factory replacement kits looks wise(mandrel bends), fit was good and all 2.5" with Aerochamber mufflers at that time. Last I saw it, came with turbo mufflers. It was a noticeable gain over the shrunk down in one section single exhaust with a glass pack on my 88 CSC. I actually kept the back half and replaced the Y pipe with a compact X and custom 2.5" dual front pipes and Sanderson shorties. That made a big difference pulling my boat in the hills with my 88 and acceleration too. You need a different cat flange, I believe. If available, it is a very nice system, just not resto points correct. Good luck.
